Where is magnetic strip used?

The plastic or glass dish does not absorb microwaves and is not heated directly. The food inside the dish heats up and then transfers some of that heat to the dish by conduction.

When food is heated in a microwave, the microwaves excite the water molecules present in the food, causing them to vibrate and generate heat, which in turn cooks the food. However, most plastic and glass dishes are transparent to microwaves, which means that they do not absorb microwaves and do not get hot. The reason for this is that the microwaves have a much larger wavelength than the size of the molecules in the plastic or glass.

Answer:

gravity

Explanation:

gravity pulls you down so for example you will weigh more on earth than on the moon because earths gravitational pull is greater.

Answer:

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

The scaling law for volume displacement, v(t, p), in terms of scaling exponents aₜ and aₚ is given by v(t, p) = aᵥ / (∂G/∂(λₐ⋅t)).

The scaling law for v(t, p) in terms of aₜ and aₚ, we can start with the given expression for the Gibbs energy scaling function:

λG(t, p) = G(λₐ⋅t, λₐ⋅p)   ---(1)

We differentiate this equation with respect to pressure (p) while treating t as a constant:

∂(λG)/∂p = (∂G/∂p)⋅(∂(λₐ⋅p)/∂p)

The derivative of λₐ⋅p with respect to p is λₐ. Now, using the relation v = (∂p/∂G), we can rewrite the above equation as:

v(t, p) = (∂p/∂G) = (∂(λG)/∂p) / (∂(λₐ⋅p)/∂p) = (∂G/∂p) / λₐ

Since G is a function of λₐ⋅t and λₐ⋅p, we can express ∂G/∂p as:

∂G/∂p = (∂G/∂(λₐ⋅p))⋅(∂(λₐ⋅p)/∂p)

Plugging this back into the equation for v(t, p), we get:

v(t, p) = (∂G/∂(λₐ⋅p)) / (λₐ⋅(∂(λₐ⋅p)/∂p))

Now, substitute the scaling function λG(t, p) from equation (1) into the above equation:

v(t, p) = (∂(λG)/∂(λₐ⋅p)) / (λₐ⋅(∂(λₐ⋅p)/∂p))

Simplifying further, we obtain:

v(t, p) = (∂(G(λₐ⋅t, λₐ⋅p))/∂(λₐ⋅p)) / (λₐ⋅(∂(λₐ⋅p)/∂p))

Using the chain rule of differentiation, we can rewrite the numerator as:

∂(G(λₐ⋅t, λₐ⋅p))/∂(λₐ⋅p) = (∂G/∂λₐ⋅t)⋅(∂(λₐ⋅t)/∂(λₐ⋅p))

Since (∂(λₐ⋅t)/∂(λₐ⋅p)) = (∂t/∂p), we can further simplify the expression:

v(t, p) = (∂G/∂λₐ⋅t) / (λₐ⋅(∂t/∂p))

Introduce the volume displacement scaling factor aᵥ as:

v(t, p) = aᵥ⋅(∂G/∂λₐ⋅t) / (λₐ⋅(∂t/∂p))

Comparing this equation with the desired form v(t, p) = aₜ⋅(∂t/∂p), we can conclude that:

aₜ = aᵥ / (∂G/

Let's call the length of the race track as "x".

To solve for "x", we can use the formula:

\(\implies\text{ Time} = \dfrac{\text{ Distance}}{\text{ Speed}}\)

Since the race ends in a tie, we know that Jan and Mary both took the same amount of time to run the race. Let's call this time "t".

\(\implies \text{ Time} = \dfrac{\text{ Distance}}{\text{ Speed}}\)

\(\implies t = \dfrac{x - 25}{7.5}\)

\(\implies\text{ Time} = \dfrac{\text{ Distance}}{\text{ Speed}}\)

\(\implies t = \dfrac{x}{8.0}\)

Since both expressions represent the same time, we can set them equal to each other and solve for "x":

\(\implies \dfrac{x - 25}{7.5} = \dfrac{x}{8.0}\)

Multiplying both sides by 60 (the least common multiple of 7.5 and 8.0) to get rid of the decimals:

\(\implies 8(x - 25) = 7.5x\)

\(\implies 8x - 200 = 7.5x\)

\(\implies 0.5x = 200\)

\(\implies x = 400\)

\(\therefore\) The length of the race track is 400 meters.

Answer:

Explanation:

Given:

V₀ = 3.0 m/s

H = 5.2 m

__________

L - ?

Time for the ball to fall vertically:

H = g·t²/2;    ⇒    t = √ (2·H / g) = √ (2·5.2 / 9.8) ≈ 1.0 c

Move the ball horizontally:

L = V₀·t = 3.0·1.0 = 3.0 m

If a boy throws a ball with a horizontal velocity of 3.0 m/s, from a height of 5.2 m over the ground , then the horizontal displacement of the ball is 3.09 meters.

There are three equations of motion given by Newton,

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

As given in the problem If a boy throws a ball with a horizontal velocity of 3.0 m/s, from a height of 5.2 m over the ground

S = ut + 1/2 × a × t²

5.2 = 0 + 0.5 × 9.8 ×  t²

t² = 5.2 / 4.9

t = 1.03 seconds

The horizontal displacement of the ball = 1.03 × 3

                                                                  = 3.09 meters

Thus, the horizontal displacement of the ball is 3.09 meters.

Answer:

The mass of the other planet is 7.23*10^(30) kg

Explanation:

For two objects of masses m₁ and m₂ respectively, separated by a distance r, the gravitational force between them is given by:

F = G*(m₁*m₂)/r^2

Where G = 6.67*10^(-11) m^3/(kg*s^2)

Here, we know that:

r = 4.5*10^8m

m₁ = 2.1*10^21 kg

F = 5*10^24 N

And we want to find the mass of the other planet, first, let's isolate m₂ in the force equation:

(F*r^2)/(G*m₁) = m₂

Now we can replace all the values that we know in the left side, and solve it:

m₂ =[(5*10^24 N)*( 4.5*10^8m)^2]/[6.67*10^(-11) m^3/(kg*s^2)*2.1*10^21 kg]

m₂ = 7.23*10^(30) kg

The mass of the other planet is 7.23*10^(30) kg

(a) The magnitude of the electric dipole moment is  0.0270 pC m

(b) The difference between the potential energies for the two orientations is 7.38 mJ and U_antiparallel is -3.69 mJ.

(a) The magnitude of the electric dipole moment can be calculated using the formula:

p = q * d

where q is the magnitude of each charge and d is the separation between the charges. Plugging in the values, we get:

p = 3.60 nC * 7.50 * 10^-6 m = 0.0270 pC m

(b) The difference between the potential energies for the two orientations can be calculated using the formula:

ΔU = p * E

where p is the electric dipole moment and E is the electric field strength. The potential energy is proportional to the dot product of the electric dipole moment and the electric field. So when the dipole moment is parallel to the electric field, the potential energy is at a maximum, and when it's antiparallel, the potential energy is at a minimum.

For the orientation parallel to the electric field:

U_parallel = p * E = 0.0270 pC m * 1370 N/C = 3.69 mJ

For the orientation antiparallel to the electric field:

U_antiparallel = -p * E = -0.0270 pC m * 1370 N/C = -3.69 mJ

The difference between the two potential energies is:

ΔU = U_parallel - U_antiparallel = 3.69 mJ - (-3.69 mJ) = 7.38 mJ

So the difference in potential energy between the two orientations is 7.38 mJ.

Newton's investigations of gravity explain the truth that Jupiter has more moons than Earth.

The fact that Jupiter has more moons than Earth was first discovered by Galileo Galilei in 1610, and it was later confirmed by Newton. In addition to having more moons, it is also thought that Jupiter may be home to some of the most powerful magnetic fields in the solar system.

Every particle in the cosmos attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers, according to Newton's law of universal gravitation.

Thus, the equation for universal gravity has the following structure:

The elastic shortening of the post is 0.00739 in (approx).

Given information:

Post is 14ft tall, W14x74 section with cross-sectional area A=21.8 in², made of steel (Esteel = 29 x 10³ ksi)

To find out the elastic shortening, use the below formula, e = (P*L) / (A*E)

Where e is the elastic shortening, P is the axial load on the post, L is the length of the post, A is the cross-sectional area of the post, and E is the Young's modulus of the material used.

Here, the cross-sectional area is A = 21.8 in² and Young's modulus is Esteel = 29 x 10³ ksi.

We need to calculate the axial load P. To find out the axial load on the post, use the below formula, P = w*L Where w is the weight of the post per unit length and L is the length of the post.

Substitute L = 14 ft = 168 in and A = 21.8 in² in the above formula and find out the weight per unit length, w = A*L = 21.8 in² * 168 in = 3662.4 in³

Convert in³ to ft³ by dividing by (12 in / ft)³,w = 3662.4 in³ / (12 in / ft)³ = 2.12 ft³

The steel density is ρ = 490 lb/ft³ (approx).

The weight of the post per unit length,

w = V * ρ = 2.12 ft³ * 490 lb/ft³ = 1038.8 lb/ft

Substitute L = 168 in and w = 1038.8 lb/ft in the above formula to get the axial load,

P = w*L = 1038.8 lb/ft * 168 in = 174422.4 lb

Substitute P = 174422.4 lb, L = 168 in, A = 21.8 in², and Esteel = 29 x 10³ ksi in the formula for elastic shortening,

e = (P*L) / (A*Esteel)= (174422.4 lb * 168 in) / (21.8 in² * 29 x 10³ ksi)= 0.00739 in

The time taken for the coffee to cool from 93°C to 73°C is approximately 36.1 minutes.

The cooling law is given by:

$$\frac{dQ}{dt}=-k(T-T_0)$$

where Q is the heat in the object, t is the time taken, T is the temperature of the object at time t, T0 is the temperature of the environment and k is a constant known as the cooling constant.

We need to find the time it takes for the coffee to reach a drinking temperature of 73°C given that its initial temperature is 93°C.

Therefore, we need to find the time it takes for the coffee to cool down from 93°C to 73°C when placed in a room temperature of 18°C.

Let’s assume that the heat energy that is lost by the coffee is equal to the heat energy gained by the environment. We can express this as:

dQ = - dQ where dQ is the heat energy gained by the environment.

We can substitute dQ with C(T-T0) where C is the specific heat capacity of the object.

We can rearrange the equation as follows:

$$-\frac{dQ}{dt}=k(T-T_0)$$

$$-\frac{d}{dt}C(T-T_0)=k(T-T_0)$$

$$\frac{d}{dt}T=-k(T-T_0)$$

The differential equation above can be solved using separation of variables as follows:

$$\frac{d}{dt}\ln(T-T_0)=-k$$

$$\ln(T-T_0)=-kt+c_1$$

$$T-T_0=e^{-kt+c_1}$$

$$T=T_0+Ce^{-kt}$$

where C = e^(c1).

We can now use the values given to find the specific value of C which is the temperature difference when t=0, that is, the temperature difference between the initial temperature of the coffee and the room temperature.

$$T=T_0+Ce^{-kt}$$

$$73=18+C\cdot e^{-0.09t}$$

$$55=C\cdot e^{-0.09t}$$

$$C=55e^{0.09t}$$

$$T=18+55e^{0.09t}$$

We can now solve for the value of t when T=93 as follows:

$$93=18+55e^{0.09t}$$

$$e^{0.09t}=\frac{93-18}{55}$$

$$e^{0.09t}=1.3636$$

$$t=\frac{\ln(1.3636)}{0.09}$$

Answer:

Hee answer is B

Explanation:

____________.

The rate at which the force is doing work on the object is 710 watts.

To calculate the rate at which the force is doing work on the object, we need to use the formula for work:

Work = Force × Distance × cos(θ)

where θ is the angle between the force and the direction of motion. In this case, the object starts from rest, so the angle between the force and the direction of motion is 0 degrees (cos(0) = 1).

Net force (F) = 142 N

Mass of the object (m) = 26.0 kg

Distance (d) = 5.00 m

First, we calculate the magnitude of the force:

F = ma

where a is the acceleration of the object. Since the object starts from rest, the initial velocity (u) is 0, and we can use the equation:

v^2 = u^2 + 2ad

where v is the final velocity.

Since the object starts from rest, the equation simplifies to:

v^2 = 2ad

Solving for v:

v = √(2ad)

v = √(2 × 142/26.0 × 5.00)

v ≈ 5.18 m/s

Now, we can calculate the rate at which work is done:

Work = F × d × cos(0)

Work = 142 N × 5.00 m × 1

Work ≈ 710 joules

Since work is the energy transferred per unit time, the rate at which work is done, or power (P), is given by:

Power = Work / time

However, the time is not given in the question. Therefore, we cannot calculate the exact power value.
